I have a chi squared of 0.1185 with 1 degree of freedom. How can i determine the P-value?

By p-value I presume you mean "the probability of seeing a value of my test statistic as large as this, if it really comes from a $\chi^2$ distribution with one degree of freedom". So if you get a low p-value it means it is an improbable value to have seen.
The p-value is very large because your value of the test statistic is actually considerably less than the average value of such a $\chi^2$ random variable. If anything, it is unusually small. So basically, you do not have a large value and hence there is not evidence to dismiss the hypothesis that it genuinely comes from a $\chi^2$ distribution.

The upper tail of the $\chi^2_1$ distribution, beyond 0.1185 is
That's your p-value
